[xsl] Abstracting XSLT to generate multiple forms for the same data schema

["Johnathon Wright" <jw@xxxxxxxxxxxxx>]

I'm trying to make my life easier. This is something which invariables 
leaves it more complicated. Anyway, our web stores run off an XSLT / XML 
engine in PHP. It works well, but coding each of tables I needed for 
different data types (users, configurations, etc., etc.) was a mess... so 
I'm trying to abstract all that. The XML and XSLT for one thing I've already 
got working is below.

My question is this: I now want to create a template that looks at the data 
types, creates a row for displaying such data, and displays it all. But that 
would require loops running through seperate nodes and I totally don't 
understand how to do that. Any comments about or help with the idea or the 
implementation would be appreciated.
